3-D Sound

Using DirectX Audio, you can locate sounds in space and can apply Doppler shift to moving sounds.

3-D effects are applied to individual DirectSound buffers. Because you can direct different sounds along different audiopaths, each with its own buffer, it's easy to apply different parameters to different sounds.

The following topics cover some general aspects of 3-D sound:

• Coordinates of 3-D Space
• Perception of Sound Positions
